Performance Fabric Stocklots: Polyester, Spandex and Moisture Claims
The direct answer: performance claims on stocklots are cheap to print and cheap to fake, so verify them by touch and by specification rather than by label. A genuine moisture-wicking knit feels smooth and thin and dries quickly; a poly-cotton with the same print feels heavier and dries slowly.

What the claims mean in practice
Moisture-wicking is a surface and yarn-structure property, not a chemical finish that can be added cheaply. Genuine wicking fabric moves liquid along the fibre and dries quickly; a fabric that simply absorbs water feels cold and heavy for far longer.
Stretch from spandex blends genuinely improves fit and recovery, but the percentage matters. A small elastane content gives comfort; a high content gives the snappy feel that survives repeated wear, and it also changes how the garment should be washed.
Testing a sample yourself
The simplest test costs nothing: drop a wet swab on the fabric and time how long it takes to dry. Then stretch the garment and check whether it returns to shape. Those two tests separate most genuine performance fabric from a printed imitation.
Ask for the composition by percentage rather than a fibre name. A supplier who cannot state the blend is usually working from a supplier list rather than from knowledge of the goods, which is a useful signal in itself.
Care labelling and resale reality
Performance fabrics need specific care, and wrong labelling causes returns. Check that the care label matches the actual composition, because a garment labelled for machine washing when the blend needs gentle handling will generate complaints you cannot resolve.
For resale, mid-weight versatile pieces in black and neutral colours move fastest, while bright technical pieces are easier to sell online but attract more returns from customers who expected a technical garment.

Buyer questions, answered
How can I tell if performance fabric is genuine?
Test a sample directly: check how quickly a wet patch dries and whether the garment returns to shape after stretching. Genuine wicking fabric dries fast and feels light; an imitation with the same print absorbs water and stays heavy much longer.
Why should I ask for composition percentages?
Because a fibre name alone hides the blend, and the blend determines how the garment wears, stretches and must be washed. A supplier who cannot state percentages is usually repeating a supplier list rather than knowing the goods.
What care labelling issues cause returns on performance clothing?
A care label that does not match the actual blend causes returns, because the customer washes it as instructed and it damages. Check the label against the composition before the lot ships, since that is much cheaper than handling complaints afterwards.
